The recent use of 3D laser scanning in the archaeological context requires techniques and systems to make the generated data usable. In this paper, we focus on the fragment reassembly based on ArcheoTUI, a tangible interface created to assemble the digitals models of fragments manually. We present a semi-automatic system to assist the user in real time in when assembling the fragments. This approach allows to use both the accuracy of geometric algorithms and the scientific knowledge of the archaeologist. The user specifies an approximate initial position of the two fragments by means of the tangible interface. Then, our system performs a real time registration thanks to the use of the Iterative Closest Point registration algorithm combined with a speed-up data structure and a bi-factorial weighting of the pairs. The data structure is used to find an area of interest on each object and to accelerate the pairs generation, whereas the weighting improves the detection of the data relevance.
